Automatically filling fountain pen



Nov. 22, 1932. c. ZORN AUTOMATICALLY FILLING FOUNTAIN PEN Filed Feb. 10,- 1932 S uunuuum 5 Patented Nov. 22, 1932 UNITE STATES CARL ZORN, OF MUNICH, GERMANY AUTOMATICALLY FILLING FOUNTAIN PEN Application filed February 10, 1932, Serial No. .582,104;, and. in Germany February 11, 1931.

This invention relates to an automatically filling fountain pen with a rubber hose for the ink located in the tubular holder and exerting a suction effect, and with a flexible 5 blade spring, one end of which spring 1s adapted to be shifted in axial direction by means of a rotatable handle for bending the spring prior to the filling.

This invention has for its object, to enable the operation of the blade spring by the simplest possible construction for right handed as well as left handed people in any easy manned and so that the blade spring is automatically secured against accidental operation. With this object in View a handle is provided adapted to be turned and consisting of a ring pushed over the holder and connected with the axially shiftable end of the blade spring by means of a transverse pin on one element guided in an inclined groove of the other element.

An embodiment of the invention is illustrated by way of example in the accompanying drawing in which Fig. 1 shows the fountain pen in elevation.

Fig. 2 is a longitudinal section on line 22 of Fig. 1.

Fig. 3 shows in elevation the tubular body of the fountain pen.

Fig. 4 is a section through the body on line 44 of Fig. 3.

Fig. 5 is a cross section on line 5-5 of Fig. 8.

Fig. 6 shows in elevation the turnable handle with inclined guide groove directed in opposite direction as in Fig. 1.

Fig. 7 shows in elevation the turnable handle with an angular guide groove.

Fig. 8 is a vertical sect-ion through the turnable ring or handle.

Fig. 9 shows in elevation a blade spring as used in connection with the turnable ring shown in Fig. 8.

5 In the sleeve or body I; of the fountain pen a rubber hose 0 is located, which is known per se and serves for sucking in the ink. This rubber hose 0 is pushed over the rear end f of the head piece a, g, h of the fountain pen.

The open end of the rubber hose 0 is simply pulled over the piece. In the sleeve b'a blade spring e is located at the f side'of the rubber hose 0, said spring hearing at the front end against the screw threaded portion 9 of the head piece. The spring has at "it'srear end a coupling projection 71.. This projection n engages with an inclined guide m of a turnablering Z located between the sleeve 7) andthe rear cap 71. The inclined guide'bonsists either of a slot or of a groove. The rear portion of the blade spring 6 carrying'the" coupling projection a is 'lo{ cated, axially shift-able, in an external ver tical groove u of the'sleeve b and extends into this groove from the interior of this sleeve through an aperture is." I The inclined guide groove m in the turnable ring Z extends from right to left for right handed people. as shown in Fig. 1, and from left to right for left'handed peopleas shown in Fig. 6.' If one and the same fountain pen has to be used by right handed as well as by left handed people the inclined guide m has two arms inclined in opposite directions as shown in Fig. 7. The apex p of the angle is formed by the two grooves forming the point for the inoperative position of the coupling projection n. In order to ensure a uniform compressing of the rubber hose a pressure bar (Z may be provided acting upon the blade spring 0.

As shown in Fig. 6, the guide m consisting of a slot can be covered by a protecting ring 7' as shown in Fig. 6, this ring being preferably arranged between milled beads s on the upper and lower ends of the turnable ring Z. The inclined guide m, instead of being arranged in the turnable ring Z, may be arranged, as shown in Fig. 9 in an enlarged portion 6 of the blade spring 6, the coupling projection n being then arranged, as shown in Fig. 8, in the turnable ring Z.

If the turnable ring Z is turned from right to left, from the position shown in Fig. 1 towards the coupling position a, this coupling projection is pushed forward and shifts forward the rear end of the blade spring 0 so that the compressing of the hose 0, necessary for the automatic filling, is effected by tubular socket h of the head the bending of the blade spring 6. This curved position of the blade spring is indi cated in Fig. 2 in dash lines.

If the turnable ring Z, after the point g of the holder has been dipped into an inkpot, is released again, this ring 1 is automatically returned into its initial position by the expanding blade spring 6, the rubber hose 0 being thus liberated to expand and to suck in the ink.

I claim: 1 a 1. An automatically filling comprising in combination a'tubular body, a head piece on the front end of said body, a

closing cap-on the rear-end of s'aid'bo dy, a

rubber hose in saidbody, a blade spring at the side of said rubber hose, a turnable ring between the rear end of said body and said cap, and a coupling device between said turnable ring and said blade spring consisting oi a coupling projection on oneofs'aid elements and of an inclined guide'on theiotherv of said ele ments; 'm

'2. An automatic fountain pen specified in claim lgin which the coupling, projection is arranged on the reai e'nd of the blade spring and an angular guide is'arranged in the turnable ring so that the device can serve as, well for right handed as for left handed people.

3; An automatically filling fountain pen as specified in claim 1, comprising in combination with the turnable ring having an inclined guide slot, a protecting ring turnable on said turnable ring designed to cover said guide slot.

Intestimony whereof I aflix my signature.
